What medications are safe to take for morning sickness?

Vitamin B6 : Vitamin B6 capsules once or twice a day can help relieve nausea. Also try chewing crystallized ginger or ginger capsules 3 times a day. Doxylamine is an over-the-counter sleep aid that can help morning sickness, take it at nighttime first as it will make you drowsy, but it can be taken every 6 hours. There are also prescription meds that your doctor can give you for severe nausea.

Very few: Check with your ob, as there are very few and the list changes with new scientific information.

Zofran (ondansetron): Zofran (ondansetron) seems pretty effective and is generally well tolerated. However its best to take nothing if you can handle it.

New prescription Rx: An old medication was recently reap proved for morning sickness... Bendectin. It was pulled off the market years ago but the fda voted to allow it back in with a new name.. Diclegis. It's just b6 and doxylamine (both things mentioned in other answer i believe).
